If she was infested, then they should have treated her for that condition. It would have made for a nice impromptu hazmat drill. Kinda like a Karen Silkwood scrubdown scenario. /Two Dogs
It is up to the patient to treat themselves when they have a bedbug or lice infestation.
If they have no shame, and are willing to infect a hospital- then all I have to say is that they are trash.
Hospital personnel have better things to do than to debug patients who come in for an elective procedure.
